A Case of Early Gastric Cancer with Synchronous Multiple Bone Metastases

The prognosis of an early gastric cancer (EGC) is generally excellent, with a 5-year survival rate of 90% in most reports; however, there have been few reports of EGC with distant metastases. Recently we encountered a rare case of EGC with synchronous multiple bone metastases. A 43-year-old woman visited a local clinic due to back pain. Lumbar spine metastases were suspected by MRI. She was transferred to our hospital and underwent bone marrow biopsy which revealed an adenocarinoma. After endoscopic evaluation for primary cancer work-up, we found a suspicious EGC lesion. The results of endoscopic biopsy was signet ring cell carcinoma. Our pathologist additionally reviewed the bone marrow biopsy slides and found signet ring cells in it. PET CT showed disseminated multiple bone metastases but, there wasn't any other malignant lesion. Here we report a rare case of EGC with synchronous multiple bone metastases.

A Case of Multicentric Castleman's Disease Presenting with Follicular Bronchiolitis / 결핵및호흡기질환

Multicentric Castleman's disease (CD) is a rare atypical lymphoproliferative disorder, which is characterized by various systemic manifestations. Some patients with multicentric CD may have concomitant lung parenchymal lesions, for which lymphoid interstitial pneumonia (LIP) is known to be the most common pathologic finding. Follicular bronchiolitis and LIP are considered to be on the same spectrum of the disease. We describe a case of multicentric CD with pulmonary involvement, which was pathologically proven as follicular bronchiolitis.

Sensitivity of Whole-Blood Interferon-Gamma Release Assay According to the Severity and the Location of Disease in Patients with Active Tuberculosis / 결핵및호흡기질환

BACKGROUND: The clinical manifestation of M. tuberculosis infection ranges from asymptomatic latent infection, to focal forms with minimal symptoms and low bacterial burdens, and finally to advanced tuberculosis (TB) with severe symptoms and high bacillary loads. We investigated the diagnostic sensitivity of the whole-blood interferon-gamma release assay according to the wide spectrum of clinical phenotypes. METHODS: In patients diagnosed with active TB that underwent QuantiFERON(R) (QFT) testing, the QFT results were compared with patients known to be infected with pulmonary tuberculosis (P-TB) and extra-pulmonary TB (EP-TB). In addition, the results of the QFT test were further analyzed according to the radiographic extent of disease in patients with P-TB and the location of disease in patients with EP-TB. RESULTS: There were no statistical differences in the overall distribution of QFT results between 177 patients with P-TB and 84 patients with EP-TB; the positive results of QFT test in patients with P-TB and EP-TB were 70.1% and 64.3%, respectively. Among patients with P-TB, patients with mild extents of disease showed higher frequency of positive results of QFT test than that of patients with severe form (75.2% vs. 57.1%, respectively; p=0.043) mainly due to an increase of indeterminate results in severe P-TB. Patients with TB pleurisy showed lower sensitivity by the QFT test than those with tuberculous lymphadenitis (48.8% vs. 78.8%, respectively; p=0.019). CONCLUSION: Although QFT test showed similar results between overall patients with P-TB and EP-TB, individual sensitivity was different according to the radiographic extent of disease in P-TB and the location of disease in EP-TB.

The clinical and microbial characteristics of healthcare-associated pneumonia / 대한내과학회지

BACKGROUND/AIMS: Healthcare-associated pneumonia (HCAP) occurs outside hospitals, but its characteristics are similar to those of hospital-acquired pneumonia (HAP). We evaluated the clinical and microbial characteristics of HCAP in Korea. METHODS: Of 130 subjects with suspected pneumonia, 49 were classified as HCAP and 81 as HAP. We retrospectively examined the clinical presentations, outcomes, pathogens, and drug resistance rates of Pseudomonas aeruginosae in both groups. RESULTS: The clinical presentations, including the symptoms and laboratory findings, at the time of hospitalization were comparable in both groups. The hospital mortalities of HCAP (28.6%) and HAP (34.6%) did not differ significantly; the length of the hospital stay was similar for all of the survivors (14 vs. 17 days, respectively). Of the identified pathogens, methicillin-resistant Staphylococcus aureus was significantly less common in HCAP than in HAP (two vs. 18 cases, respectively, p<0.01), whereas Klebsiella pneumoniae was more common in HCAP (five vs. zero cases, respectively, p<0.01). The frequency of other Gram-negative rods was similar in both groups. The rate of resistance to antibiotics in P. aeruginosae in both groups was substantial, with the highest resistant rate to ciprofloxacin (50% and 61.5% in HCAP and HAP, respectively). CONCLUSIONS: Although the clinical features and outcomes of HCAP were comparable to those of HAP in the study population, the frequency of methicillin-resistant S. aureus was significantly lower in HCAP compared to HAP.

Comparisons of Clinical Characteristics and Outcomes in COPD Patients Hospitalized with Community-acquired Pneumonia and Acute Exacerbation / 결핵및호흡기질환

BACKGROUND: Data comparing the clinical characteristics and outcomes in chronic obstructive pulmonary disease (COPD) patients hospitalized with community-acquired pneumonia (CAP-COPD) and acute exacerbation (AE-COPD) are very limited. METHODS: Eighty episodes of hospitalization in 65 CAP-COPD patients, and 111 episodes of hospitalization in 82 AE-COPD patients were included in this study. The baseline characteristics, clinical presentations, potential bacterial pathogens and clinical outcomes in these patients were retrospectively reviewed and compared. RESULTS: No significant differences were found between the two groups in parameters related to COPD and co-morbidities, except a higher rate of male among CAP-COPD patients. Clinical presentations by symptoms and laboratory findings on admission were significantly more severe in CAP-COPD patients, who showed higher rates of fever and crepitation, but less wheezing than AE-COPD patients. S. pneumoniae and P. aeruginosae were the most common bacterial pathogens in both groups. With no difference in the overall hospital mortality between both groups, the mean length of hospital stay was significantly longer in the CAP-COPD patients than in AE-COPD patients (15.3 vs. 9.8 days, respectively, p<0.01). Additional analysis on CAP-COPD patients showed that systemic steroid use did not influence the length of hospital stay. CONCLUSION: Although there was no significant difference in bacterial pathogens and overall hospital mortality between the two groups, CAP-COPD patients had more severe clinical symptoms and laboratory findings at presentation, and longer hospital stay than AE-COPD patients.
